From publisher blurb:
THE MINIMALIST ROLEPLAYING GAME OF SURF, SUN & SAFETY
Powered by the lightweight, yet versitile TinyD6 system, BEACH PATROL allows you to take on the role of lifeguards in all their slow-motion glory! This book features new TinyD6 rules such as SLO-MO MODE, vehicle training, and Lifeguard Traits, as well as adventure generators for BEACH PATROL and it's crazy paranormal older sibling BEACH PATROL: NIGHTS.
This is a full-game, but doesn't spend lots of pages or text talking about what roleplaying games are. It assumes some familiarity with roleplaying games, and their tropes and play. The text reflects that.
